ST-45
4-piston caliper
DISCONTINUED CALIPER

At this time, we do not have any pads for ST-45 calipers.

The ST-45 4-piston caliper was used in limited applications from 1999 to 2012, before being discontinued.  It was primarily included with truck and SUV big brake kits with 15" rotors, but also used on 14" REAR brake kits for the Nissan 350Z and Infiniti G35.

The ST-45 caliper was based on the ST-40, but utilized a slightly taller pad, allowing it to clear 15" rotors or suspension features that otherwise prevented ST-40 calipers from being used.  

If you think you have ST-45 calipers because of their appearance, it's more likely you have ST-40 calipers, especially if your application does not use 15" rotors.  If you are unsure, contact us before ordering any parts.
